I'm losing more an more my English ....
My speaking skill has greatly reduced, my writing is going the same way ...
Somebody to help me !
Thanks in advance
practice it so you'll never lose it.
For example ... instead of writing your daily notes in your native language .. write them down in English.
In your way to work/college ..listen to Audio books in English or to the news.
if you have a close friend who can speak English .. talk to him in English whenever you meet him.
Basically ... surround yourself with English (:
